Hi everyone,
We enjoy the renewed "Hepta" SRC engine in Pyramix 7, but on the other hand we are quite unhappy with its performance. On an up-to-date Core i5 workstation the generation of a CD Image from a plain 24 bits/96 kHz stereo project, using one of the 3 available "SRC Filter Types", takes almost real time, approx. 1 hour for a 70 minutes disc image. All three CPU cores (the forth one is hidden due to MassCore) are constantly running at 100% load. With mixdowns the performance is identical, so this doesn't seem to be a problem with the "Generate CD Image" module only.
We are using the current 7.1.10 version - not quite sure if the performance has maybe become worse with one of the past Pyramix versions.
Anyone having similar problems?
Regards,
Daniel

Re: Hepta SRC performance
Hi Daniel,
Sounds like you have something not working quite correctly with your system. My 24/96 stereo projects with dither added via Ozone 4 mix down at about 3-4 times realtime on my old P4D system (about 5 times when going to a 32-bit floating file without Ozone). Even a large 24-track 24/96 project with automation is faster (though not by much!) than realtime. Still using XP but with the latest PMX build.
Cheers,
Tom

Re: Hepta SRC performance
Hi Tom,
Thanks for your reply. I found out that obviously the virus protection was causing the huge performance problems. I had deactivated it already before, but obviously something was still disturbing Pyramix in the background. After a complete uninstall the speed is about six times fast than before.
Best wishes
Daniel

Re: Hepta SRC performance
Too happy too soon. It was not the anti-virus software, but obviously this is really a Pyramix issue. From time to time there are still poor mixdown performances - sometimes a restart of Pyramix (just the application, not a Windows reboot) helps, sometimes it doesn't. Haven't found out what the problem is yet.
